"Tragically the hard work and determination of hundreds of search and rescue professionals and volunteers has not resulted in finding Carson," Sugar Bowl Ski Resort said in a statement.

The sheriff’s office said they have not located Carson and did not find any clues to his whereabouts.

"Placer County Sheriff’s personnel, Sugar Bowl representatives and chaplains met with the May family [Tuesday] and it is with regret that we must suspend the efforts to locate Carson," the sheriff's office said in a news release.

"Our heartfelt thoughts and prayers go to the May family, who have been dealing with the unthinkable these past five days," Sugar Bowl said. "The May family and Sugar Bowl will work together moving forward to try to find some sense of closure."

While there will be no active search, "should new information become available and environmental conditions allow, additional follow-up searches may occur," the sheriff's office said.

The sheriff's office said May went out during white out conditions Thursday. Sugar Bowl saw snowy conditions, gaining 5 inches of snow overnight at the summit and 3 inches of snow at the base.

On Saturday, crews narrowed their search to an area two-tenths of a mile long, thanks to pings from May’s cellphone. That location received several feet of snow since May was last seen Thursday. The increased snowfall over the weekend also created avalanche-prone areas in the back country.

"Conditions during the five days of searching have been treacherous due to frequent heavy snow and the associated risks that high avalanche danger poses to the many search and rescue volunteers," the sheriff's office said.

More than 400 volunteers and professionals helped in the search for May, Sugar Bowl said. Seven avalanche search dogs and three helicopter teams also took part in the search.

Carson May is a Mountain Sports Learning Center ski instructor. He is from Davis but now lives in Truckee.
